A writer named James Bender once revealed in his book, “How to Talk Well” [New York; McGray-Hill Book Company, Inc., 1994], about a farmer who grown excellent-quality corns, and often won awards from his achievements.
One day, a journalist of local newspaper interviewed him, and unveiled his success’ secret.
He surprisingly found that the farmer used to dispersed his seeds to his neighbors before they started to grow the corns.
“How could you share your corn seeds to your neighbors, and then compete in the same competition every year?” he asked astonishingly.
The farmer simply replied, “Don’t you know that winds blow pollens from the near-fruited corn, from one field to another? If my neighbor grown low quality corn, it will affect my corn when the cross-fertilization occur. Thus, if I want to produce top quality corns, I must help them to grow good corns too.”
